LINWOOD A. HORD, OF ADAMSTON, WEST VIRGINIA.

ROTARY ENGINE.

Application filed. January 29, 1907, Serial No. 354:,669. Renewed May 2,1908.

To all whom it "may concern:

Be it known that 1, LINWOOD A. Horn), a citizen of the United States,residing at Adamston, in the county of Harrison, State of Nest Virginia,have invented certain new and useful Improvements in Rotary Engines; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to rotary engines and more particularly to thatclass in which the cylinder of the engine forms the rotary member, theshaft being non-rotatable.

In carrying out my invention I employ a cylinder having heads whichrotate therewith and a piston which is located within the cylinder andaround which the cylinder rtates. This piston is of ordinary construction, including slidable blades or heads against which the steamimpinges and upon the piston and concentrically thereof are formedcollars, there being one collar on each side of the piston and connectedwith these collars or formed integral therewith is the en gine. Uponeach of the cylinder heads there is formed a pair of concentric flangesthe inner one of which embraces the corresponding collar and engagedover the outer flanges of each pair is a steam chest in communicationwith which is a steam inlet pipe. A steam port is formed in eachcylinder head and has communication with the respective steam chest andalso at times, with the cylinder itself.

In the accompanying drawings, Figure 1 is an edge view of an engineconstructed in accordance with my invention, Fig. 2 is a side elevationthereof with one of the cylinder heads removed, Fig. 3 is a detailvertical longitudinal sectional view, taken centrally therethrough andshowing the inlet port of the engine closed.

Referring more specifically to the drawings the engine is shown ascomprising a cylinder 5 having heads 6. The cylinder is hollow but has aportion of its inner periphery eccentric to the remaining portionthereof as in dicated by the numeral 7 and arranged within the cylinderis a piston 8 which is circular in form and is provided with slidableblades or heads 9 which contact at their ends with the inner peripheryof the cylinder and are moved by the eccentric portions 7 thereof whenone of their ends is in engagement with 1 the engine.

the said portion, to bring their opposite end into engagement with theremaining portion. Each of the cylinder heads is provided with anopening 10 through which projects a collar 11 which is formed integralwith the corresponding side of the piston 8. The engine shaft ispreferably formed in sections 12 which are connected or formed integralwith the collars 11.

Formed integral with each cylinder head 6 is a pair of concentricflanges, the inner one being indicated by the numeral 13 and the outerone by the numeral 141 and the inner flange extends around the opening10 in its respective cylinder head and surrounds or embraces the collar11. The collars of each pair are suitably braced as at 15 and formed ineach cylinder head is a radially extending port 16 which hascommunication at its inner end with the interspace between the flanges13 and 1 1 and at its outer end, at all times with the inter-spacebetween the main portion of the inner periphery of the cylinder and theopposing portion. of the periphery of the piston.

The outer flange 14 is provided with a plurality of grooves 17 andfitted over each of these flanges 1 1 is a cylindrical steam chest 18which is provided upon its inner periphery with a plurality of spacedribs 19 which seat in the grooves 1 7. To permit suchfltting of thesteam chest over the flange, each of the steam chests is slit atdiametrically opposite points and is provided upon opposite sides ofeach slit with ears 20 which are apertured for the passage of bolts 21upon which are engaged nuts 22, it being understood that these bolts ornuts serve as a means for tightening the engagement of the chest uponthe flanges. Each of the steam chests 18 is reduced at a point slightlyoutwardly of or beyond the end of the collar 11 as at 23 to iit aroundthe shaft 12, there being ribs 24: formed upon the shaft and projectinginto grooves 25 in the reduced portions of each steam chest. This meansof connecting the steam chests with the flanges 14 and with the shaftserves to form an effective packing to prevent escape of steam and alsoserves to hold the parts in their proper relation. Communicating witheach of these steam chests 18 is a steam inlet pipe 26 and 'these pipesare connected with a steam main 27 and are each provided with a cut-oflvalve 28 whereby steam may be admitted to either side of the piston toreverse A steam exhaust pipe 29 also leads from each steam chest and isprovided I with a suitable cut-off valve and it will be l readilyunderstood that when steam is being admitted to the engine at one side,the exhaust pipe from the steam chest at the opposite side is open, theexhaust at the first mentioned side'being of course closed.

From the foregoing description and from I the drawings it will beobserved that the cylinder itself is the only member which re volves andit is hence used as the fly wheel of the engine.

What is claimed is,

1. An engine of the class described comprising a rotary cylinder, apiston arranged within the cylinder, said piston being stationary,concentric flanges formed upon the heads of the cylinder, said headshaving inlet ports formed therein and communicating with the interspacebetween the flanges and with the cylinder, shafts connected with theopposite sides of the piston, steam chests I engaged over the outer oneof the concentric flanges upon the cylinder heads and connected with theshafts, an inlet communicating with each steam chest and an exhaustleading therefrom 2. An engine of the class described comprising arotary cylinder, a piston arranged within the cylinder, said pistonbeing stationary and including heads, concentric flanges formed uponeach of the heads, collars carried by the piston at opposite sidesthereof and embraced by the corresponding inner flanges of each pair,said heads having inlet ports formed therein and communicating with theinterspace between the pairs of flanges and with the cylinder, saidinlet ports being extended in different directions, nonrotatable steamchests secured over each of the outer flanges of the pair, each of theouter flanges being provided in its outer periphery with a plurality ofgrooves, ribs formed upon the outer periphery of each steam chestprovided within the grooves in the flanges, an inlet communicating witheach steam chest and an exhaust leading from each steam chest.

In testimony whereof, I affix my signature, in presence of twowitnesses.
